Well, Python is not Raku, so while it could be possible to make "[expr1, expr2, ..., exprN] * exprM" to mean "[*(expr1), *(expr2), ..., *(exprN) for _ in range(exprM)]", it would never happen.

Besides, that still doesn't help with the case of

    x = function_that_returns_a_list()
    x = x * 4

where there is no literal list expression.
